This invention relates to improvements in display devices for advertising purposes.

- Broadly, it is an object of my invention to provide a display device which will give the appearance of the bubbling or eiervescence of many known beverages, tablets and pills that discharge gasses when brought in contact with liquids.

Moreparticularly, it is an object of my invention to provide an aerator or air pressure device for use with advertising displays for drinks of various types or drinks mixed with other liquids, such as liquors, or mixed with sparkling or carbonated soda and ginger ales, etc., to simulate the rising bubbles known to such liquids or medical compounds.

A further objectof my invention is to provide a display device having a recircularization of air. A further object of my invention is to provide a display device having a closed container for the fluid to .prevent evaporation, overflowing, and the possibility of dirt and dust entering the container and fluid.

Heretofore, devices have been known for display purposes for liquids, which have open tops so that the iiuid has to be constantly replaced or added because of evaporation. If alcoholic beverages are used, such as beer, a head or foam is created which overruns the top of the container causing loss of the beer and soiling of the display device. The open container causes germs, dirt and dust to collect, causing the parts,

Fig. 2 is an enlarged section taken on. line o 2-2 of Fig. 1.

Fig. 3 is taken on line 3-3 of Fig. 2. Fig. 4 is a bottom elevational -view or the com.- pressor.

Fig. 5 is taken on line 'l-l of Fig. 2. Referring to the drawings. reference numeral I0 Arepresents a display device, having a base I2 in the form of a container. On the upper member II of base I2, there is mounted an inverted glass container I3. Within the base I2 and on the bottom wall I4 of the base I2, there 5 is mounted an electric socket I5 to receive bulb I6 which may be of any desired color. Base I2 may have attached thereto background I'l for carrying out a sales display. 'I'he background II may be changed to take any desired shape and base I2 may take the shape of the package of the advertiser or any other desired shape. At the same time, it can be usedto conceal the .necessary parts, such as the electric bulb and socket, the base of the glass container and any other necessary Working parts.

The glass container I3 has a shoulder I8, which rests upon upper member II of the base I2. The narrower lower portion I9 of container I3 projects into base I2 through an opening in 20 upper member II. -Cover 20, having a rubber washer 2| cov'ers the open bottom of container I3, and is attached preferably by a screw thread 22, or may be sealed'with a vacuum cap (not shown). A vacuum thus created in container u I3 will make easier pump action since the atmospheric pressure is eliminated.

Cover 20 has two openings through which are fastened an inlet member 23 and an outlet valve 24. Inlet member 23 has fastened to the upper portion a rubber tubing 25, upon which is mounted a block of porous material 26, which may be of carborundum, sandstone, pumice, siliconcarbide, meerschaum, or similar material. A glass or Celluloid tubing 21, open at the top andA extending just below the upper part of the glass container I3, is attached to outlet valve 24 by rubber tubing 5'I.Y

Inlet member 23 and outlet valve 24 are attached to a plate 28. A plate 29 is separated 40 from plate 28`by a fibre ring 30 forming a compartment 3l. Within compartment 3|, there is a valve 52 through which air is forced into compartment 3|. Another bre ring 32 has attached toits lower part an inverted U-shaped plate 45 33 having a central opening 34 through which a laminated core 35 passes. By using a laminated core, eddy currents will be prevented and the unit will not become excessively overheated.

A rubber diaphragm 36 is held in position 50v upon core 35 between upper washer 31 and lower washer 38 by screw 40. A cushion of soft rubber 39 is mounted below washer 38 to absorb the shock of the movement of core 35.

The rubber diaphragm 36 is held in position 55 between plate 23 and bre'ring 32 by screws 4| so that an air compartment42 is created.

Attached to plate 33 by screws 43 is a U- shaped core 44 having a sleeve 45. In the center of sleeve 45 there is a screw 45 having a cap 41 and a stop 43 for adjustment of the laminated core 35.

Plate 33 and U-shaped core 44 have slots 49 and U, respectively, to prevent eddy currents and keep plate 33 and core 44 from becoming excessively heated.

Between core 44 and laminated core 35 there is an electric coil 5|. Spacing exists between electric coil 5| and the sides of laminated core 35 and between the bottom of core 35 and stop 48 to allow for vertical movement of core 35 as indicated by the arrow in Fig. 2.

By passing an electric current through electric coil 5|, laminated core 35 moves vertically upward and downward, causing rubber diaphragm 36 to force air from compartment 42 through valve 52 into compartment 3l. When air is forced through valve 52, it raises the washer 54 permitting the air to pass through wire mesh 55 into compartment 3|. The wire mesh 55 limits the movement of the washer 54. The air thence passes through opening 53 and through the passage in inlet member 23 and rubber tubing 25 and through the pores of the porous material 23. The air thus forced through the porous material 26 rises through the iluid in glass container I3 and then rises to the top of the container, entering the glass or Celluloid tubing 2l, returning through outlet valve 24 and compartment connecting tube 56 and Vinto compartment 42 again to repeat its cycle. It will thus be seen that`V compartment 42 is both a compression and a suction chamber.

It is obvious that various changes and modications may be made in the details of construction without departing from the general spirit of the invention, as set forth in the appended claims.
